High potency marijuana that hits the lungs hard when smoked, with a really strong creeper high that invokes borderline paranoia and extreme cotton mouth. Lungbuster strains will keep even veteran smokers glued to the couch unable to move, novice users will probably have anxiety and loss of motor control. Good lungbuster strains are usually indica and include OG Kush, Sour Grapes, Purple Erkle, Bubba Kush, and Cherry Pie to name a few.
That Sour Lemon Larry was some lungbuster!! i can barely breathe. Yeah, everytime i go to that club, their top shelf is some straight lungbuster...only need one good bong rip to get high as a parasail.
